simplify (3sqrt(x-1))(3sqrt(x+1))

simplify

(3 x - 1) (3 x + 1)

9 x - 1 x + 1

Solution steps

(3 x - 1) (3 x + 1)

Apply exponent rule:

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

3 \cdot 3 = 3^{1 + 1}

= x - 1 \cdot 3^{1 + 1} x + 1

Add the numbers:

1 + 1 = 2

= x - 1 \cdot 3^{2} x + 1

3^{2} = 9

= 9 x - 1 x + 1

3^{\frac{3}{4}}

0.000123 \cdot 1 0^{- 8}

4.83 \cdot 1 0^{- 10}

4440 \cdot (2.7 \cdot 1 0^{- 11})

9.93256 \cdot e^{- 5}
