Ответ:

a) $4^3+3^5=64+243=307$

б) $(-8)^2-(-1)^{10}=64-1=63$

в) $7\cdot( \frac{-3}{7})^2=7\cdot \frac{9}{49}=\frac{9}{7}=1\frac{2}{7}$

4. $5a^6\cdot (-3a^2b)^2=5a^6\cdot 9a^4b^2=45a^{10}b^2$

5. $(6x^2-7x+4)-(4x^2-4x+18)=6x^2-7x+4-4x^2+4x-18=2x^2-3x-14$

6. $\frac{25^4\cdot 125{10}^}{5^{37}} =\frac{(5^2)^4\cdot (5^3)^{10}^}{5^{37}} =\frac{5^8\cdot 5^{30}^}{5^{37}} =\frac{5^{8+30}^}{5^{37}} =\frac{5^{38}^}{5^{37}} =5^{38-37}=5^1 =5$
