Question

calculati: [(+5)³]⁷:[(-5)⁴]⁵+(-1)²⁰¹⁰-41​

Answer 1

Răspuns: $\bf \red{\underline{-35~}}$  

Explicație pas cu pas:  

$\bf \big[\big(+5\big)^3\big]^7:\big[\big(-5\big)^4\big]^5+\big(-1\big)^{2010}-41=$

$\bf \big(+5\big)^{3\cdot7}:\big(-5\big)^{4\cdot5}+\big(-1\big)^{2010}-41=$

$\bf 5^{21}:\big(-5\big)^{20}+1-41=$

$\bf 5^{21}:5^{20}+1-41=$

$\bf 5^{21-20}+1-41=$

$\bf 5^{1}+1-41=$

$\bf 5+1-41=$

$\bf \red{\underline{-35~}}$
