Question

c. (8×10¹⁵)+(4×10⁶)
a. (3×10⁵)×(2×10³)=□
(use the multiplication symbol in t

Explanation:

Step1: Multiply the coefficients

$3\times2 = 6$

Step2: Multiply the powers of 10

$10^{5}\times10^{3}=10^{5 + 3}=10^{8}$ (using the rule $a^{m}\times a^{n}=a^{m + n}$)

Step3: Combine the results

$6\times10^{8}$

Answer:

$6\times10^{8}$
