Question

zrobi ktos chociaz kilka?
dam naj proszee potrzebuje na teraz..​

Answer 1

a)

√(-7)^2 * (`3√2)^3 - `3√(-5)^3 = 7 * √2 - 5 = 7√2 - 5

b)

√10^2+5^3 = √2^2+5^2+5^3 = √(2^2+5)*5^2 = √(4+5)*5^2 = √9*25 = 3*5 = 15

c)

√3 6/25 = √81/25 = 9/5 = 1 4/5

d)

`3√√400 + 7 = `3√20+7 = `3√27 = 3

e)

√0,0016 = √1/625 = 1/25

f)

√100-36 = √64 = 8

g)

`3√-15 5/8 = `3√-125/8 = - 5/2 = -2 1/2

h)

`3√ 1/512*125 - √441/√400 = 1/8*5-21/20 = 5/8-21/20 = (- 17/40)

i)

√6+√6+√9 = √6+√6+3 = √6+√9 = √6+3 = √9 = 3
