Question

# Rewrite (7.7.7.7 + 5.5.5 -3.3.3) in simplest form using exponents:

- (7
^{4} + 5^{3} -3^{3}) - (4
^{7 }+5^{3} +3^{3}) - (7
^{5 }+ 5^{3} -3^{3}) - (4
^{7 }-5^{3} -3^{3})

^{4}+ 5^{3}-3^{3})^{7 }+5^{3}+3^{3})^{5 }+ 5^{3}-3^{3})^{7 }-5^{3}-3^{3})Hint:

### We have to write the given question in exponent form.

## The correct answer is: (7^{4} + 5^{3} -3^{3})

### The given value is

(7.7.7.7 + 5.5.5 - 3.3.3)

When we have a^{m} a^{n} = a^{m+n}

Here we have 7.7.7.7=7^{1+1+1+1}

=7^{4}

5.5.5 = 5^{1+1+1}

= 5^{3}

3.3.3 = 3^{1+1+1}

= 3^{3}

So, (7.7.7.7+5.5.5-3.3.3) = (7^{4} + 5^{3} -3^{3})

Sometimes if the power is not one, we have to be careful while adding that.
