How do you multiply #(3.3 × 10^4) *(3 × 10^18)#?

Answer 1

Julia Adams

Regroup your terms and use the rule for multiplying common based exponents: #b^pxxb^q = b^(p+q)#

Regrouping: #(3.3 xx 10^4) * (3xx10^18)# becomes #(3.3xx3) * (10^4xx10^18)#

#= 9.9 xx 10^22#

To multiply ( (3.3 \times 10^4) \times (3 \times 10^{18}) ), you multiply the coefficients (3.3 and 3) and add the exponents (4 and 18) together to get:

[ (3.3 \times 3) \times 10^{4+18} ]

[ = 9.9 \times 10^{22} ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
