Answer 1

Te puedo ayudar con todos menos con la raiz xd

12 – 10 + (6 x 52 )

=2+(6)(52)

=2+312

=314

100 ÷ 5 + 25 x 3 =

=20+(25)(3)

=20+75

=95

12 - 3 (10 x 8)

=12−(3)(80)

=12−240

=−228

8 – 6 – (6 x 5) + 62

=2−(6)(5)+62

=2−30+62

=−28+62

=34

2[4-3](2)]+20

=(2)(1)(2)+20

=(2)(2)+20

=4+20

=24

2[8-8(7-3)+2(5)]

=2(8−(8)(4)+(2)(5))

=2(8−32+(2)(5))

=2(−24+(2)(5))

=2(−24+10)

=(2)(−14)

=−28

3[30+10]-9

=(3)(40)−9

=120−9

=111

4{[15÷3]-(8-5)}÷8

=4(5−(8−5))÷8

=4(5−3)÷8

=(4)(2)8

=8÷8

=1

21+{(2(15-3)-(3)(7)]+(3)(8)}

=21+(2)(12)−(3)(7)+(3)(8)

=21+24−(3)(7)+(3)(8)

=21+24−21+(3)(8)

=21+3+(3)(8)

=21+3+24

=21+27

=48
