First, let's simplify each term inside the parentheses:
(-2a^3)^2 = 4a^6(-b^5c)^3 = -b^15c^3(b^6)^2 = b^12(2.6a^4)^2 = 6.76a^8
Now, we can multiply all the simplified terms together:
4a^6 (-b^15c^3) b^12 * 6.76a^8
= 4 -6.76 a^6+8 b^12+15 c^3
= -27.04a^14b^27c^3
So, the simplified expression is -27.04a^14b^27c^3
First, let's simplify each term inside the parentheses:
(-2a^3)^2 = 4a^6
(-b^5c)^3 = -b^15c^3
(b^6)^2 = b^12
(2.6a^4)^2 = 6.76a^8
Now, we can multiply all the simplified terms together:
4a^6 (-b^15c^3) b^12 * 6.76a^8
= 4 -6.76 a^6+8 b^12+15 c^3
= -27.04a^14b^27c^3
So, the simplified expression is -27.04a^14b^27c^3
