Question

2⁶ + 3
4² + 5²
47²-37²- 23² algm me ajuda pfvr eu tentei mais nn consigo

Answer 1

Resposta:

2⁶ + 3 = 67

4² + 5² = 41

47² - 37² - 23² = 311

Explicação passo a passo:

$2^{6} +3=2^{(3\times2)} +3=(2^{3} )^{2} +3=8^{2} +3=64+3=67$

$4^{2} +5^{2} =16+25=41$

$47^{2} -37^{2} -23^{2}=\\\\(47-37)\times(47+37)-23^{2}= \\\\10\times84-23^{2}= \\\\840-23^{2} =\\\\(841-1)-23^{2} =\\\\841-23^{2} -1=\\\\29^{2} -23^{2} -1=\\\\(29-23)\times(29+23)-1=\\\\6\times52-1=\\\\312-1=\\\\311$
