Question

1. copie e faça do mesmo modo.
ex:10=√100
a) 7=
b)12=
c)13=
d)15=
e)20=
f)25=
g)30=
h)50=

2.calcule.
a)√36+64
b)√36+√64
c)√4·25
d)√4·√25

Answer 1

1) 7 = √49
12 = √144
13 = √169
15 = √225
20 = √400
25 = √625
30 = √900
50 = √2500

2) √36 + 64 = 70
√36 + √64 = 14
√4 . 25 = 50
√4 . √25 = 10
