simplify sqrt(4u+1)*sqrt(4u-1)

simplify

4 u + 1 \cdot 4 u - 1

(4 u + 1) (4 u - 1)

Solution steps

4 u + 1 4 u - 1

Apply radical rule:

a b = a \cdot b,

assuming

a \geq 0, b \geq 0

4 u + 1 4 u - 1 = (4 u + 1) (4 u - 1)

= (4 u + 1) (4 u - 1)

99.9 (10)^{- 3}

1.3 \cdot 10 e^{- 6}

0.51 \cdot 1 0^{- 4}
