10^(x/3+3)
=10^5, then
find the
value of 10^-
X/2
A 100
B 1/100
C 1/1000
D 1/10000​

Answer 1

Answer:

I think it's option D that is 1/10000

Answer 2

Answer:

Option C

Step-by-step explanation:

$lhs \: = {10}^{( \frac{x}{3} + 3) } \\ x \: = 6 \\ so \: lhs \: = {10}^{ \frac{6}{3} + 3 } = {10}^{2 + 3} = {10}^{5}$

LHS =RHS

$find \: {10}^{ - \frac { x }{2} } \\ = {10}^{ - \frac{6}{2} } = {10}^{ - 3} \\ = \frac{1}{1000}$
