Question

Perform the following operationand express the answer inscientific notation.7.15x103 x 6.10x10-5[ ? ]x10?Coefficient (green) Exponent (yellow)Enter

Answer 1

Answer:

$\text{ 43.62 }\times10^{-2}$

Explanation:

Here, we want to perform the given mathematical operation

To do this, we take the like terms together and arrange them

We have this as:

$\begin{gathered} \text{ 7.15 }\times\text{ 6.10 }\times10^3\text{ }\times10^{-5} \\ =\text{ 43.615 }\times10^{3-5} \\ =\text{ 43.615 }\times10^{-2} \end{gathered}$

We write the final answer in 3 significant figures too as follows:

$\text{ = 43.62 }\times10^{-2}$
