Answer:

Step-by-step explanation:

2³[1/4 + 4(36÷12) ] = 2³[1/4 + 4*(3) ]

=2^{3}*[\frac{1}{4}+12]= 8*[\frac{1}{4}+\frac{12*4}{1*4}]\\\\=8*[\frac{1}{4}+\frac{48}{4}]\\\\=8*\frac{49}{4}\\\\=2*49=98

-(-6/7)x(6/7) what is the correct product
-Dominant- [34]
-( \frac{-6}{7} )* (\frac{6}{7})

Remove parentheses : (a) = a

\frac{6}{7} * \frac{6}{7}

Apply exponent rule : a^b.a^c =  a^{b+c}

\frac{6}{7} * \frac{6}{7} = ( \frac{6}{7}) ^{1+1}  = (\frac{6}{7} )^{2}

Apply exponent rule:

(\frac{a}{b})^c = \frac{a^c}{b^c}

\frac{6^2}{7^2}  =  \frac{36}{49}

hope this helps!.

Two staments that show the relationship between the values of the numbers 0.5 and 0.05
nirvana33 [79]
<span> The place value relationship of 0.5 and 0.05 in the given number
=> 0.5 and 0.05 are decimal numbers because they are place next to the decimal points.
=> 0.5 placed next to decimal point is tenths and 0.05 is in hundredths.
Now, what’s the relation of both numbers?
=> 0.5 is 10 times greater than 0.05
=> How? Let’s try solving it
= 0.5 = 5/10
=> 0.05 = 5/100
=> 0.05 x 10 = 0.5
=> 0.5 + 0.05 = 0.55
