Question

What is (3 X 10^3) +(2.5 X 10^6)? *

Answer 1

Answer:

Scientific Notation: 2.503 × 10⁶

Standard Form: 2,503,000

Answer 2

Hey there!

$\mathsf{(3 \times 10^3) + (2.5 \times 10^6)}$

$\mathsf{= 3 \times 10^3 + 2.5 \times10^6}$

$\mathsf{10^3}$

$\mathsf{= 10 \times 10 \times 10}$

$\mathsf{= 100 \times 10}$

$\mathsf{\bf = 1,000}$

$\mathsf{10^6}$

$\mathsf{= 10 \times 10 \times 10 \times 10 \times 10 \times 10}$

$\mathsf{= 100 \times100 \times100}$

$\mathsf{= 10,000\times100}$

$\mathsf{= \bf 1,000,000}$

$\mathsf{= 3\times 1,000 + 2.5 \times 1,000,000}$

$\mathsf{3\times1,000}$

$\mathsf{\bf = 3,000}$

$\mathsf{2.5 \times 1,000,000}$

$\mathsf{\bf = 2,500,000}$

$\mathsf{3,000 + 2,500,000}$

$\mathsf{= \bf 2,503,000}$

$\boxed{\boxed{\large\textsf{Answer: } \mathsf{ \bf 2,503,000 \ or \ 2.503 \times 10^6}}}\huge\checkmark$
