Answer 2

Hey there!

$\mathsf{(7 \times 10^8) - (4 \times10^6)}$

$\mathsf{= 7\times10^8 - 4\times10^6}$

$\mathsf{10^8}$

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

$\mathsf{= 100 \times 100 \times 100\times 100}$

$\mathsf{= 10,000\times10,000}$

$\boxed{\mathsf{\bf = 100,000,000}}$

$\mathsf{7\times100,000,000 - 4 \times10^6}$

$\mathsf{10^6}$

$\mathsf{= 10 \times 10 \times 10 \times 10 \times 10\times10}$

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

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

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

$\mathsf{7 \times 100,000,000 - 4 \times 1,000,000}$

$\mathsf{7\times100,000,000 = \boxed{\bf 700,000,000}}$

$\mathsf{700,000,000 - 4 \times1,000,000}$

$\mathsf{4\times 1,000,000 = \boxed{\bf 4,000,000}}$

$\mathsf{700,000,000 - 4,000,000}$

$\boxed{\mathsf{= \bf 696,000,000}}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf 696,000,000}}}\huge\checkmark$
