Question

What is the value of x in this equation? Enter your answer in the box.​

Answer 1

Answer:

x = 6

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Consider

10³ × $10^{x}$ = $10^{9}$, then

$10^{3+x}$ = $10^{9}$

Equating exponents

3 + x = 9 ( subtract 3 from both sides )

x = 6

Answer 2

Answer:

x=6

Step-by-step explanation:

Create equivalent expressions in the equation that all have equal bases, then solve for x.
