who knows these?
x=2, y+3, a=4over 5 as a fraction, b=3 over 5 as a fraction.
1) 23-(a+b)
2) (10x)2 (2 is an exponent) +100a
3) a2(2 is an exponent)+2b
4) x+z divided by xz
5) (z divided by x)2(the exponent) +ax
please just dont give me the answers, but actually explain in steps how you got the answer. thanks!

1) 23 – (4/5 + 3/5) = 23 – 7/5 = 115/5 – 7/5 = 108/5
2)(10x)^2 + 100a = (20)^2 + 80 = 480
3) a^2 + 2b = 16/25 + 6/5 = 16/25 + 30/35 = 46/25
4)(2+z)/2z = I need the value for z…
5) (z/2)^2 + 8/5 = I need the value for z…
I don’t have the value for z, but I wrote the equation out

HOPE IT HELPS!!
1) 23- (a+b)
23-(4/5+3/5)=
=23-(7/5)=
=23-1and 2/5=
=23-1,4=
=21,6
2) 100×2(2 is an exponent) + 100a=
=100×2 + 100*4/5=
=100×2 + 80=
= 100*4 +80=
=480
3) a2 +2b=
=a2+ 6/5=
=16/25 + 30/25=
=46/25= 1 and 21/25
z=?
