Question

please Bata do. please. ​

Answer 1

Answer:

after that

2^n+2=32/8

2^n+2=4

2^n=4-2

2^n=2

2^n=2^1

compare

n=1

Answer 2

Given :-

$➝\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 8 \times {2}^{n + 2}$

To Find :-

$➝ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 8 \times {2}^{n + 2} = 32 \: \: \: \: \: \: \:$

_______________________________

$➝ \: \: \: {(2)}^{3} \times {2}^{n + 2} = {2}^{5}$

Here, Apply law of exponents :-

$➝ \: \: \: x^{a} \times {x}^{b} = x ^{a + b}$

so,

$➝ \: \: \: {2}^{3 + n + 2} = {2}^{5} \\ \\ ➝ \: \: \: 2^{5 + n} = 2 ^{5} \: \: \: \:$

we finally use law of exponents

$➝ \: \: \: 5 + n = 5 \\ \\ ➝ \: \: \: n = 5 - 5 \\ \\ ➝ \: \: \: n = 0 \: \: \: \: \: \: \: \:$

Answer :- n = 0

I hope it helps you.
