Question

(4×10^7) ×(6×10^-5)/8×10^4 plzzz solveee

Answer 1

Given "(4×10^7) ×(6×10^-5)/8×10^4 "

We know that

[ x ^(-n) = 1 / x^n]

apply this formula

(4×10^7) ×(6×10^-5) / 8×10^4

((4 × 10^7 ) × (6/10^5)) / 8 × 10^4

We know that [x^n /x^m = x ^ (n - m)

Applying this formula

[(4(10 ^(7-2))/6 ] / [8 × 10^4]

[(4(10 ^5 /6 ] / [8 × 10^4]

4 and 6 with 2..

[(2(10 ^5 /3 ] / [8 × 10^4]

[(2(10^(5-4))/ 3] / [ 8]

[(2(10^ (1) / 3] / [ 8]

[(2(10/ 3] / [ 8]

[20/3] / [8]

[20 ] / [3(8)]

20 / 24

dividing numerator and denominator with 4..

5/6 .....is the answer...
