simplify (4ysqrt(+)5)(ysqrt(-)5)

simplify

(4 y + 5) (y - 5)

100 - y^{2}

Solution steps

(4 y + \cdot 5) (y - \cdot 5)

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

5 \cdot 5 = 5^{1 + 1}

= 4 y + y - \cdot 5^{1 + 1}

Add the numbers:

1 + 1 = 2

= 4 y + y - \cdot 5^{2}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

yy = y^{1 + 1}

= 4 + y^{1 + 1} - \cdot 5^{2}

Add the numbers:

1 + 1 = 2

= 4 + y^{2} - \cdot 5^{2}

5^{2} = 25

= 4 \cdot 25 - y^{2}

Multiply the numbers:

4 \cdot 25 = 100

= 100 - y^{2}

(3 a b^{2})^{3}

ln (6.59 x) 1 0^{- 3}

\frac{58 1 ^{2}}{48 7 ^{2}}

\frac{1 ^{2}}{e ^{2}}
