Multiply (2.4 x 10^14) x (4 x 10^7). express the answer in scientific notation a. 9.6 x 10^21 b. 9.6 x 10^22 c.96 x 10^21 d.96 x 10^22

b

Step-by-step explanation:

Start with PEMDAS ( Parenthesis Exponents Multiplication Division Addition Subtraction)

start with the INSIDE of the parenthesis and for the next step of PEMDAS is exponents so 10^14 is also equal to 1,000,000,000,000,000 rewrite the problem

(2.4×1,000,000,000,000,000) × (4 ×10.7) multiply the 2.4 times the other number simplify

24,000,000,000,000,000 × (4 × 10^7)

work on the other side of the parenthesis. same steps

100,000,000 simplify

24,000,000,000,000,000 × (4 × 100,000,000) multiply again

24,000,000,000,000,000 × 400,000,000 multiply again

to make this part simpler im going to use a calculator

the answer to this problem is going to be B
