simplify 9sqrt(8rs)-5sqrt(8rs)+7sqrt(8rs)

simplify

9 8 rs - 5 8 rs + 7 8 rs

222 r s

Solution steps

9 8 rs - 5 8 rs + 7 8 rs

Add similar elements:

9 8 rs - 5 8 rs + 7 8 rs = 11 8 rs

= 11 8 rs

Apply radical rule:

ab = a b,

assuming

a \geq 0, b \geq 0

8 rs = 8 rs

= 118 rs

Apply radical rule:

ab = a b,

assuming

a \geq 0, b \geq 0

rs = r s

= 118 r s

8 = 22

= 11 \cdot 22 r s

Multiply the numbers:

11 \cdot 2 = 22

= 222 r s

∣ 3 x + 4 ∣ \geq 13

4 x^{2} - 16

∣ x ∣ + 19 \leq 3

16 = \frac{( 9 \cdot 1 0 ^{9} ) ( 120 \cdot 1 0 ^{- 6} - y ) y}{( 1.2 ) ^{2}}

4 x^{2} - 40 x + 24
