Question

pls anybody tell
who answers first and correct answer they ill mark as brainlist

Answer 1

(2^3)^2

first method
2^3= 8
so,

(8)^2= 64

second method
(2)^3*2

(2)^6
= 64

answer is same from Both the method
so ur answer is 64

Answer 2

4]
a) (2³)²

= 2^6

= 64

b) (5²)^1/2

= 5¹

= 5

c) [(12/25)^-1]²

= (12/25)^-2

= 12^-2/25^-2

= 1/12²/1/25²

= 1/144/1/625

= 1/144×625/1

= 625/144

d) [(32/240)^-6]^0

= [(32/240)^-0

= 1

5]

a)a²×b²

= (ab)²

b)(1/3)³×(2/3)³

= 1/27×8/27

= 8/729

c)(1/5)^-8×(5/7)-8

= 1^-8/5^-8 × 5^-8/7^-8

= 1/1^8/1/5^8 × 1/5^8/1/7^8

= 1/1 × 5^8/1 × 1/5^8 × 7^8

= 7^8

= 5764801

d)(1/4)^-10 × (2/5)^-10

= 1^-10/4^-10 × 2^-10/5^-10

= 1/1^10/1/4^10 × 1/2^10/1/5^10

= 1/1 × 4^10/1 × 1/2^10 × 5^10

= (2²)^10 × 1/2^10 × 9765725

= 2^20/2^10 × 9765725

= 2^10 × 9765725

= 1024 × 9765725

= 10000000000
= 10^10
