simplify sqrt(21y)*5sqrt(49y)

simplify

21 y \cdot 5 49 y

3521 y

Solution steps

21 y \cdot 5 49 y

Simplify

21 y : 21 y

= 21 y \cdot 5 49 y

Simplify

49 y : 7 y

= 21 y \cdot 5 \cdot 7 y

Apply radical rule:

a a = a,

assuming

a \geq 0

y y = y

= 21 y \cdot 5 \cdot 7

Multiply the numbers:

5 \cdot 7 = 35

= 21 y \cdot 35

= 3521 y

A (A + B)

\frac{6 ab}{( a ^{0} b ^{2} ) ^{4}}

(12 - 9 n^{2} + 5 n^{3}) - (- 11 n^{3} - 4 n^{2} + 6 n)

e^{x^{2} + 5 l n (x)}

10 \cdot 0! + 3! + 9 \cdot 1!
