Question

2³ . 5² - 10¹⁷ : 10¹⁵ + 2021⁰

Answer 1

=8.25-100+1

=101

Answer 2

\(=8.25-10^2+1\)

\(=200-100+1\)

\(=101\)

Answer 3

\(2^3.5^2-10^{17}:10^{15}+2021^0\)

\(8.25-10^2+1\)

\(200-100+1\)

\(100+1=101\)

Answer 4

TA CÓ:\(2^3.5^2-10^{17}:10^{15}+2021^0\)

\(=2^3.5^2-10^2+1\)

\(=2^3.5^2-2^2.5^2+1\)

\(=5^2.\left(2^3-2^2\right)+1\)

\(=5^2.4+1\)

\(=101\)

Answer 5

2³.5²-10¹⁷:10¹⁵+2021⁰

=8.25:10²

=8.25.100

=200.100

=20000
