Question

evaluate the following giving your answers in standard form to 2dp
(8.08 * 10 raise to Power 7) *(5.5 * 10 raise to power 5 )​

Answer 1

Answer:

The answer in standard form is $44.44 \times 10^{12}$

Explanation:

The given Statement is

(8.08 * 10 raise to Power 7) *(5.5 * 10 raise to power 5 )​

This can be written as

$(8.08 \times 10^7) \times (5.5 \times 10^5)$

Combining the like terms i.e., the numerical terms and the terms with powers we get

=>$(8.08 \times 5.5 )\times (10^7 \times 10^5)$

=>$(44.44 )\times (10^{7+5} )$    since $a^m\cdot a^n = a^{(m+n)}$

=>$(44.44 )\times (10^{12})$

$(8.08 \times 10^7) \times (5.5 \times 10^5)$ =  $(44.44 )\times (10^{12})$
