Simplify the expression using properties of exponents. -16a-3b-5 2a-4b2

Step-by-step answer

P Answered by PhD

$a^n\cdot a^m=a^{n+m}\\\\-16a^{-3}b^{-5}\cdot2a^{-4}b^2=(-16\cdot2)(a^{-3}a^{-4})(b^{-5}b^2})\\\\=-32a^{-3+(-4)}b^{-5+2}=\boxed{-32a^{-7}b^{-3}}$

Mathematics

Simplify the expression using properties of exponents

Step-by-step answer

P Answered by PhD

Option A

Step-by-step explanation:

This is because whenever you have a negative exponent, you put it to the reciporical value of it. If you have two same exponenet bases, you add them up.

PLEASEE HELPP....Simplify the expression using properties of exponents.

Step-by-step answer

P Answered by PhD

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{n} }{a^{m} }$ = $\frac{1}{a^{(m-n)} }$

Given

$\frac{25a^{-5}b^{-8} }{5a^{4}b }$

= $\frac{25}{5}$ × $\frac{a^{-5} }{a^{4} }$ × $\frac{b^{-8} }{b^{1} }$

= 5 × $\frac{1}{a^{(4-(-5))} }$ × $\frac{1}{b^{(1-(-8))} }$

= 5 × $\frac{1}{a^{9} }$ × $\frac{1}{b^{9} }$

= $\frac{5}{a^{9}b^{9} }$ → D

Simplify the expression using properties of exponents.

Step-by-step answer

P Answered by PhD

$\dfrac{12a^{-9}b^{-4}}{9a^2b^6}=\dfrac{12:3}{9:3}a^{-9-2}b^{-4-6}=\dfrac{4}{3}a^{-11}b^{-10}\\\\=\boxed{\dfrac{4}{3a^{11}b^{10}}}\to \boxed{B.}\\\\\text{used:}\\\\\dfrac{a^n}{a^m}=a^{n-m}\\\\a^{-n}=\dfrac{1}{a^n}$

How do you simplify this expression using properties of logarithms? 1/4 log4 16

Step-by-step answer

P Answered by PhD

Step-by-step explanation:

$\frac{1}{4} \: log_4 16 \\ \\ = \frac{1}{4} \: log_4 {4}^{2} \\ \\ = \frac{1}{4} \times 2\: log_4 {4} \\ \\ = \frac{1}{4} \times 2\: \times 1 \\ \\ = \frac{1}{2} \\ \\ \huge \blue{ \boxed{\therefore \: \frac{1}{4} \: log_4 16= \frac{1}{2} }}\\$
