3/4b-1/6=1/2×b
1.75b=.3
b=0.2
I believe this is right. But not 100%
<span> 3h2 • (h + 7) • (h + 1) is the simplified version.</span>
dy/dx = 8(8x - 5)(4x² - 5x )^ 7
differentiate using the ' chain rule '
dy/dx = 8(4x² - 5x)^ 7 × d/dx (4x² - 5x)
= 8(4x² - 5x)^ 7 × (8x - 5)
= 8(8x - 5)(4x² - 5x)
No it's as n example of a equality
