Evaluate Using Scientific Notation (210^58)(2*10^-27)

$(2 \cdot 10^{58}) \cdot (2 \cdot 10^{- 27})$

Step 1

Multiply $2$ by $2$ .

$4 (10^{58} \cdot 10^{- 27})$

Step 2

Multiply $10^{58}$ by $10^{- 27}$ by adding the exponents.

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$4 \cdot 10^{58 - 27}$

Subtract $27$ from $58$ .

$4 \cdot 10^{31}$
