Question

What number should be the exponent on the 10 so that the two numbers are equivalent? 75.6 - 10% = 0.00756 y = -3 C y = 3 c y y = 4 y = 4 =

Answer 1

y = -4

Step-by-step explanation:

Given the equation:

`75.6*10^y=0.00756`
`\begin{gathered} 0.00756=7.56*10^(-3) \\ =75.6*10^(-4) \end{gathered}`

Thus, the number is -4.
