[square root (8x^9y^4)]²=8x^9y^4

[3x^4y^2 square root (2x)]²=9x^8y^4 .2x=18x^9y^4
the answer is
square root (18x^9y^4=
B. 3x^4y^2 square root (2x)

square root (2)- square root (10)/ square root (2)+square root (10)

(√2-√10) /√2+√10=(√2-√10) (√2-√10)/(√2+√10)(√2-√10 )=(√2-√10)²/2-10
2+10-2√5/-8=(√5-6)/4, it is the same of
A. -3/2+1/4 square root (10)

27^2/3 =∛27²=∛3^3)^2=∛3^3x2=∛3^2)^3=3^2=9

the answer is
C. 9

Neil places £2000 in a bank account that pays 1.5% simple interest per year. How much interest will he earn in 6 years?

Step-by-step answer

P Answered by PhD

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

You can buy jars of the same jam in 2 sizes large jar:440g for £1.54 small jar:340g for £1.26 By considering the price per gram, work out which jar is the best value for money. Working must be shown

Step-by-step answer

P Answered by PhD

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
