Question

please help me I need your help ​

Answer 1

${( \frac{1}{2} )}^{6} - {( \frac{3}{4} + 1)}^{3} \\ = \frac{1}{128} - \frac{343}{64} \\ = \frac{1 - 686}{128} \\ = \frac{ - 685}{128}$

Answer 2

Step-by-step explanation:

a=1/2

b=3/4

then,

a⁶-(b+1)³

=(1/2)⁶-[b³+1³+3b(b+1)

=1/64-[(3/4)³+1+3*3/4(3/4+1)]

=1/64-[27/64+1+9/4*7/4]

=1/64-27/64(1+16/4)

=-26/64*(1+4)

=-26/64*5

=-13/32*5

=-65/32

=-2.03125

hope this helps you
